ことになる。Next, the operation will be described. When power is supplied to the heater (17) and the motor (20), the heater (17) generates heat and the fan (22) rotates. The radiant heat of the heater (17) is irradiated below the guard (10) through the slots (14) (14), and the heater directly hits the upper surface of the fan (22). One that reflects on the outlet (5) and reflects on the upper surface of the fan (22) and the through hole (24) of the fan (22)
(24) The light passes through the guard (10) after passing through and is reflected and split into those that hit the lower surface of the fan (22). For this reason, a part of the radiant heat of the heater (17) is absorbed by the fan (22) by the black processing (25) and (26), but since the fan itself is constantly rotating during use, it acts as a heat sink. It acts and becomes hot air, and is discharged from the discharge part (15).
この結果、実験によると、ガード(10)の温度は約10
4℃(従来は約120℃)、所定間隙(11)内のP点(図示

反対にユニット内の温度を低くすることができることは
ヒータ(17)の発熱量を高くすることもできる。As a result, according to experiments, the temperature of the guard (10) was about 10
4 ° C. (conventionally about 120 ° C.), the temperature at the point P (the part where the temperature protector is mounted, not shown) in the predetermined gap (11) is about 91
° C (conventionally 106 ° C), and the temperature was low in any part. This means that if the heating value of the heater (17) is the same, heat is efficiently released to the outside,
Conversely, lowering the temperature inside the unit can also increase the amount of heat generated by the heater (17).

分な効果があった。By the way, in the configuration shown in FIG. 2, when the black processing is applied only to the upper surface of the fan (22) facing the heater (17), the temperature of the guard (10) is about 108 ° C. Is about 95 ° C and the black color is guarded by the fan (22) guard (10)
When only the lower surface facing the side is applied, the temperature of the guard (10) is approximately 114 ° C., the temperature of the point P is approximately 102 ° C., and only one surface of the fan (22) is blackened. Also had a sufficient effect.

内の温度上昇を抑えることができる。FIG. 3 shows another embodiment, in which a lower surface of a reflecting plate (3) provided below a decorative plate (2) is provided. A motor (20) is fixed to the upper surface of the center of the support, and a fan (22) fixed to the motor is arranged between the reflector (3) and the heater (17). In addition, a guard (10) is provided below the heater (17), and the lower surface of the fan (22) facing the heater (17) is blackened (34). As a result, the radiant heat of the heater (17) is divided into one that irradiates downward through the guard (10) and one that irradiates the lower surface of the fan (22). Although heat is absorbed, it is efficiently released to the outside as in the case of FIG. Of course, also in this case, when the upper and lower surfaces of the fan (22) are subjected to black processing, the temperature rise in the guard (10) and the unit can be suppressed.

の効果が得られる。(G) Advantages of the Invention As described above, the present invention is such that at least one of the upper surface and the lower surface of the fan is subjected to black processing, so that the radiant heat of the heater is positively absorbed by the fan by the black processing.
Since this heat is released to the outside of the unit by the self-cooling action of the fan, it is possible to suppress a rise in the temperature inside the unit and prevent each part from becoming high in temperature. Therefore, each member of the unit can reduce the distance between each other, can further reduce the height dimension, and can efficiently discharge the radiant heat of the heater to the outside of the unit. Further, when black processing is performed on at least the upper surface of the fan facing the heater side, the minimum effect can be obtained by reducing the expensive black processing material.
